By comparison the underlying index for a cap is frequently a LIBOR rate, or a national interest rate. [1] The extent of the cap is known as its notional profile and can change over the lifetime of a cap, for example, to reflect amounts borrowed under an amortizing loan. [1] The purchase price of a cap is a one-off cost and is known as the ...
In statistics, a circumflex (ˆ), called a "hat", is used to denote an estimator or an estimated value. [1] For example, in the context of errors and residuals , the "hat" over the letter ε ^ {\displaystyle {\hat {\varepsilon }}} indicates an observable estimate (the residuals) of an unobservable quantity called ε {\displaystyle \varepsilon ...
A matrix, has its column space depicted as the green line. The projection of some vector onto the column space of is the vector . From the figure, it is clear that the closest point from the vector onto the column space of , is , and is one where we can draw a line orthogonal to the column space of .
The Black model (sometimes known as the Black-76 model) is a variant of the Black–Scholes option pricing model. Its primary applications are for pricing options on future contracts, bond options, interest rate cap and floors, and swaptions.
P i receives a hat other than h 1. This case is equivalent to solving the problem with n − 1 people and n − 1 hats because for each of the n − 1 people besides P 1 there is exactly one hat from among the remaining n − 1 hats that they may not receive (for any P j besides P i, the unreceivable hat is h j, while for P i it is h 1).

From January 2008 to May 2012, if you bought shares in companies when David C. Novak joined the board, and sold them when he left, you would have a 0.6 percent return on your investment, compared to a -4.2 percent return from the S&P 500.
A cumulative accuracy profile (CAP) is a concept utilized in data science to visualize discrimination power. The CAP of a model represents the cumulative number of positive outcomes along the y-axis versus the corresponding cumulative number of a classifying parameter along the x-axis. The output is called a CAP curve. [1]
